API Gateway is AWS's API management service. Handles routing, authentication, rate limiting, caching, request/response transformations. Advanced mastery: caching strategies, custom authorizers, WAF integration, monitoring via CloudWatch. Learning takes 2-3 weeks basic, another 3-4 for advanced patterns. Widely used in AWS-first companies. Mastery earns $120k-180k, especially for DevOps/platform engineers.

Apa iku AWS API Gateway Advanced

AWS API Gateway is a managed service for creating and managing REST, HTTP, and WebSocket APIs. It sits in front of backend services (Lambda, EC2, Fargate, DynamoDB) and handles routing, authentication, rate limiting, caching, request/response transformation, and monitoring. Advanced mastery covers caching strategies (by query param, by user), custom authorizers (JWT validation), request/response mapping (VTL), WAF integration (DDoS protection), and observability (CloudWatch, X-Ray).

❓ FAQ

What's the difference between REST API and HTTP API in API Gateway?
REST API: full-featured (auth, models, CORS, logging), slower. HTTP API: simpler, faster (optimized for Lambda), cheaper. Use REST for complex logic, HTTP for simple passthrough to Lambda.
How do you cache responses in API Gateway?
Enable caching on stage, specify cache TTL (time to live). Cache key = method + path. Sophisticated: vary cache by headers/query params. Reduces backend load significantly.
What are custom authorizers and when do you use them?
Lambda functions that validate requests (JWT, OAuth, custom logic). Runs before request hits backend. Returns IAM policy allowing/denying access. Use when: need custom auth logic beyond Cognito.
How do you handle CORS in API Gateway?
API Gateway handles CORS headers automatically. Configure allowed origins, methods, headers. Or use VTL to customize response headers.
What's VTL and why is it needed?
Velocity Template Language. Maps request to backend format (JSON → XML, etc.). Used in request/response transformations. Powerful but verbose. Try to avoid if possible.
How do you monitor API Gateway?
CloudWatch logs (request/response), metrics (latency, count, errors). X-Ray tracing for detailed debugging. CloudWatch alarms for anomalies.
Can API Gateway handle WebSockets?
Yes. Create WebSocket API, handle $connect/$disconnect/$default routes. Lambda integration for each. Good for chat, real-time updates. Lower cost than traditional WebSocket servers.
